JOSIAH C. THORNE, OF SAN JUAN, CALIFORNIA.

CALENDAR.

Application filed September 27', 1921. Serial Ito. 503,591.

To all whom it may concern Be it known that I, Josmr; C. THorNn, a citizen of the United States, residing at San Juan, in the county of San Benito'and State of California, have invented new and useful Improvements in Calendars, of which the following is a specification.

. This invent-ion relates to calendars and has for its object the provision of a novel calendar which is capable of use for many years, a plurality of rotary disks being provided which carry legends visible through openings, one of the disks bearing the numbers of the days of the months arranged in such form that'when this disk is rotated it be set to agree with any month of any year within reasonable limits, means being also provided for taking care of leap year.

An important object is the provision of a calendar of this character which is formed of a series of sections arranged in overlapping relation and capable of movement away from one another so as to expose the section lying beneath, all of the sections being capable of being secured together by a common element.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture highly efficient inuse, durable in service, and a gen eral improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Figure 1 is a front elevation of my calen-- dar ready for use,

Figure 2 is an elevation withthe forward section removed,

Figure 3 is an elevation with the inter mediate section removed,

Figure 4 is a detail view of the month name disk removed,

Figure 5 is a view of the moved, and

Figure 6 is a central vertical sectional View.

Referring more particularly to the drawings, I have shown my calendar as comprising a main supporting section 10 which is here shown as being rectangular in shape and slightly elongated but which might be of any other shape if preferred. This secyear disk retion may be constructed of card-board, celluloid or any other suitable durable and attractive material and may be ornamented or may be provided with advertising matter. At its upper end this section is preferably formed with a hole 11 by means of, which it may be suspended from a nail or the like. Disposed upon the section 10 and rotatable thereon, is a disk 12 of card-board or the like revolubly mounted on an eyelet 13 which passes through the disk and through the section 10. At its upper portion this section 10 has inscribed thereon a panel 14 which is located immediately adjacent the periphery of the disk and which is subdivided into seven parts within which are inscribed the names of the days of the week. The disk 12 is inscribed with a series of concentric lines 15 which are intersected by radial lines 16 which define columns within which are inscribed the numbers of the days of the month. The series of columns is divided by lines 17 into three groups, in one of which the numbers run no higher than thirty,lin

another of which the numbers run to '31,. and in the remaining one of which the numbers run to 28 with. an additional marking of 29 for the months of February during leap year.

Disposed upon the section 10 is an intermediate section 18 which is of less length than the section 10 and which is provided with a cut out portion 19 within which may be displayed the figures on the disk 12. This section 18 is formed with a hole 20 registering with the eyelet 13.

The numeral 21 designates the front section which is of less length than even the intermediate section 18 and which is provided with a hole 22 registering with the eyelet 13 and hole 20 and through all of these holes may be passed a suitable securing device, such as a paper fastener or the like for holding the three sections assembled. Disposed against the underside of the section 21 and rotatable upon an eyelet 23 is a disk 24- which has its peripheral portion inscribed with numbers indicating years and the number of any year may be displayed at a cut out portion 25 in the front section. This disk also carries the initials L. Y., standing for leap year, this legend being arranged opposite every fourth year number on the disk and this legend is visible through an opening 26. Opposite the disk 24, is mounted a through an opening 29. Itshould also be stated that the front section is provided with a cut out portion 30 corresponding to the cut out portion 25 at which the name of a month may be seen.

In setting the device the operator rotates the disk 24: so that the proper year number will be exposed at the cut out portion 25. The disk 27 is then turned until the desired month is visible at the cut out portion 30 and at thesame time the number of days of.

such month will be displayed within the opening 29. The operator then rotates the disk 12 to bring the proper group of numbers thereon in position at the out out portion 19, the group exposed depending upon the number appearing through the opening 29. The disk 12 is further rotated to bring the number 1 of the proper group beneath the proper day legend. on the panel 14-. and the calendarwill then be ready for use. In case of February it will be observed that the group of numbers of the days ranges from 1 to 28 but is also provided on a separate line with an additional number, namely 29, for use in leap years.

From the foregoing description and a study 01 the drawings it is believed'that the construction operation and advantages oi- -my calendar will be thoroughly understood without any necessity for a further detailed explanation. It is to be noted that the sections may be readily swung out of engagement with one another whereby to facilitate aney/7e mounted thereon and inscribed. with circu lar and radial lines defining columns within which are inscribed the numbers'o'f the days f the month, said numbers being arranged in separate groups depending upon the various numbers of days in the montlnan intermediate section pivotally mounted upon the lower edge of the main section an d terminating short of the upper end ofthe main section and provided with a cut out portion through which the numbers of any selected group on the disk may be visible, Et'fLOlll} section pivotally mounted upon the lower edge Oil? the intermediate section and pro vided with cut out portions, and disks r'o tatable upon eyelets extending through. said front sectioinone of said last named disks.

having its peripheral portion inscribed with the numbers of years visible through one sald last named openings and the other ofsaid last named disks having its peripheral portion inscribed with the names of the months visible through the other ofsaid last named openings. 7 y

In testimony whereof I my signature.
